BARCELONA – Web technology survey firm W3Techs ranked ExoClick the fourth largest online advertising network in the world, the network announced Tuesday. ExoClick claims 4.2 billion impressions daily.

Last year, the company ranked fifth on the same index.

“Throughout 2014 we introduced a number of strategically planned expansion goals,” ExoClick founder and Chief Executive Officer Benjamin Fonzé said. “Firstly, we implemented several innovative platform tools and enhancements, all designed to allow our clients to really fine tune their traffic sources by new methods of segmentation, experimentation and targeting to better monetise their [return on investment]. For example, we introduced infinite flexible frequency capping, bettering the option that Google offers by allowing retargeting of ads in minutes and hours, something that AdWords doesn’t offer. Another example is our Android App, which has made ExoClick a truly multi-device platform, giving both advertisers and publishers access and full control of their accounts via desktop or mobile device [and] allowing 24/7 access to clients from wherever they are.

“The second factor is our global mainstream growth, achieved by targeting specific traffic segments including gaming, dating, entertainment and mobile,” he continued. “Our sales team have driven new business by attending key mainstream U.S. shows, including Ad:Tech San Francisco and New York, Affiliate Summit West, and several major European shows. We have also boosted our global presence with mobile carriers in emerging and developed markets and launched an Android in-app [site development kit] to target mobile app developers.

“Thirdly, thanks to the hard work of the ExoClick team, which we have expanded significantly across all departments, and the management team’s strategic planning, we have achieved exponential growth for a privately held company.”

ExoClick also recently ranked as the 50th fastest-growing tech company in Europe, Middle East and Africa in Deloitte’s Fast 500. The network achieved a growth rate of 2,642 percent and is the only Spanish-registered company to be featured in Deloitte.

On Feb. 28, Alexa ranked ExoClick the 464^th most trafficked website on the internet, noting users view 1.87 pages within a 97-second average daily visit. According to Alexa, the company’s primary traffic sources are, in order, Germany, the U.S., India, Italy and Brazil.
